Steelheart starts off by a tragic loss. A kid loses his father to the hands of an epic. But what is an epic? In the rules of the world created by Sanderson, the world fell to shambles when Calamity, our beloved Sun, was modified. The modification gave some humans corky powers. But curiously, with each power granted, a very unspecific weakness in relation to the power tagged along. A weakness can be something as simple as a specific time of the day, or something as ridiculous as a joke. This makes the task of defeating epics a whole epic in itself. To find out an epic's weakness, one must observe and study the individual. At any rate, so are the rules of the world.
I enjoyed this audiobook very much. I would go about calling it a literary achievement. I would, however, call it an awesome-amazing-epic-adventure! You have the weapons, the high-tech, the fights, the mass destruction, the meticulous planning to take down epics, etc.
I also enjoyed the narration. It was excellent. The character development is solid, each one of them having very specific nuances in language, gait, body movements, etc.
I would recommend this book for anyone looking for a good sci-fi, fiction story. It is loads of fun, full of surprises, and enjoyable to listen to at any time.
